Amy, Amy, Amy. We thought you were getting better, not worse! Just two weeks ago, after a short stint in rehab and a clear-headed, successful performance at London’s 100 Club, it was reported that the British songbird’s sobriety was finally on the mend. But in Serbia on Saturday night, Winehouse kicked-off what was supposed to be her European tour, showing up visibly inebriated on stage. Not only could a stumbling Amy barely sing for her Belgrade audience of 20,000 ticket-holders, but her cringe-worthy “performance” was heavily booed in what local press is referring to as “the worst in the history of Belgrade.” An apologetic statement has been issued from her camp, speaking to the incident and canceling her next two shows in Turkey and Greece:

“Despite feeling sure that she wanted to fulfill these commitments, she has agreed with management that she cannot perform to the best of her ability and will return home,” a statement said. “She would like to apologize to fans expecting to see her at the shows but feels that this is the right thing to do.” (via Reuters)

While we all love a good guilty-pleasure train wreck, this substance abuse saga is only getting more and more sad. As a former VH1 You Oughta Knowartist, Amy first hit the scene in 2003 with debut album Frank, and made a splash here in the states in ’06 with sophomore LP, Back To Black. Over the next two years, the not-so-sober star took home a slew of accolades, including five Grammy awards, most notably Best New Artist, and Record of the Year and Song of the Year for, you guessed it: the no longer ironic tune, “Rehab.” Whether her chosen poison this time is drugs or drinks, it goes without saying that we wish Amy the best on her rollercoaster to recovery. Stay tuned; the 27-year old is slated to perform next at the BBK Festival in Bilboa, Spain on July 8th.
